摘　　要：为提高弹协调器的交弹效率,同时保障协调交弹动作具有高可靠度,开展某弹协调器机构的可靠性优化设计。考虑主要几何尺寸、制造误差、重要构件弹性变形等影响因素,建立某弹协调器的参数化刚柔耦合动力学模型,通过参数化动力学分析,复现协调器的协调交弹动作失效,并建立相对应的功能函数及协调器可靠性优化设计模型。针对协调器可靠性优化模型,为提高优化设计的效率和精度,构建新的Kriging模型自适应更新策略,并与序列二次规划(SQP)方法、功能函数度量法(PMA)/可靠度指标法(RIA)结合,提出协调器机构可靠性优化设计方法。研究结果表明,在协调交弹可靠度满足要求的情况下大幅提高了某协调器的协调效率,也验证了所提方法的有效性和工程价值。In order to improve the coordination engagement efficiency while maintaining the high reliability of the coordination engagement action,a reliability optimization design of ammunition coordinators was carried out.Considering the main geometric dimensions,manufacturing errors,elastic deformation of important components and other factors,a parametric rigid-flexible coupled dynamic model of ammunition coordinators was established,the failures of the coordination engagement action for coordinators were reproduced through the parametric dynamics analysis,then the performance function corresponding to the coordination failure mode and the reliability optimization design model of the coordinators were built.In order to improve the efficiency and accuracy of solving the coordinator reliability optimization design model,a new Kriging model adaptive update strategy was constructed and combined with SQP method and performance measure approach(PMA)/reliability index approach(RIA),and the coordinator mechanism reliability optimization design method was proposed.The results show that the coordination efficiency of the coordinators is greatly improved under the conditions that the coordination engagement reliability meets the requirements,and the validity and engineering value of the proposed reliability optimization design method are also verified.
